Osuna is Tyler Baum, SeMe Sung, Sergio Chavez, and Dominick Campbell. We all started playing together in San Francisco in 2000.
Nick and Sergio have been in several bands together for many years. They moved to San Francisco in 1997 and had a band called Halo which ended in 1998. Nick started the Blast Rocks with his friend Will Eskridge after that and Sergio made his own music under the name "Lo-Budge".
Meanwhile, Tyler Baum was in Virginia and SeMe Sung was in Alabama. Tyler and SeMe both moved to San Francisco in 2000 and met Sergio and Nick. All four of them started making new songs together under the name "Osuna".
Osuna is an Elementary School in Albuquerque, New Mexico.
